what is semantic html?

Semantic HTML, also known as semantic markup, is HTML that adds meaning to the web page as opposed to focusing solely on presentation. A p> tag, for instance, denotes that the contained text is a paragraph. The fact that individuals are aware of what paragraphs are and how to display them makes this presentational and semantic.

• Instead of just defining the presentation or appearance of the information, semantic HTML uses HTML markup to support the semantics, or meaning, of the information in web pages and web apps. Traditional web browsers and a wide variety of additional user agents process semantic HTML.
